Your Wireless Network should use "WPA2" Security

The best level of protection for your wireless network is called WPA2 (sometimes referred to as WPA2 AES). If your network is configured to use WEP, Open or WPA, you need to change your configuration to WPA2. Visit your router vendor's website for instructions on changing this setting. (Linksys instructions can be found here.)

Use a strong Passphrase (or better still - a random one)

Even if you are using the right security settings on your Wi-Fi, a bad password makes it too easy for attackers to break in. Make your Wi-Fi password as long as possible, ideally more than 14 characters. Don’t use words from the dictionary or easy-to-guess information about you like your name or birth date. We have more password tips here.

Don't use your wireless network name or your own name

Leaving your wireless network name set to a default like “default” or “linksys” makes cracking the password much faster and easier for a criminal. Change your network name to something unique to improve your security. However, don’t reveal too much personal information, like your name and address. Learn more about wireless networks here.

Keep your computer and web browser fully up to date (patched)

Attackers can take control of your computer and steal your sensitive information by exploiting security vulnerabilities in software. Keep your operating system, software and web browser patched with the latest security updates at all times. Learn more about securing your web browsers here.

Use a VPN

A VPN or Virtual Private Network is a very simple tool for securing your information with encryption—and then forwarding it to a secure host before it goes out to the Internet. Encryption with a VPN means that even if you join a suspicious wireless network, the attackers can’t see or modify your private information. Learn more about personal data security here.

Use HTTPS or SSL when accessing websites

HTTPS means the information is encrypted between you and the website you are visiting, providing extra security against cyber attacks. Not all websites support it, but major websites, such as Facebook and Twitter, do have it—you can tell because the web address starts with https://. You should also check that you enable the SSL option if you have an email client.

Turn off WPS

WPS is a feature that is designed to make connecting to your wireless network really easy with a short PIN, or a click of a button. You may spot it on your wireless networking equipment or in the Wi-Fi settings on your router. Attackers can gain access to your network within hours if you use WPS. Instead, use a good secure password and have your devices remember it.

Watch out for other types of wireless connections

Perhaps you carry around a mobile hotspot, or a smartphone or smart navigation system? Many of these devices allow connections via other wireless technologies, such as Bluetooth. Often these devices have a default security PIN such as 0000, 1234 or 9876. None of these are particularly difficult for an attacker to guess! Make sure you change these PINs to something secure. Where possible, limit use of "discoverable" mode so your devices aren’t as easily found by attackers. Finally, disable wireless when you don’t need it.

It's not all about PCs! You might have a wide variety of “smart” devices using wireless in your home and all around you at every moment. Your smartphone could be vulnerable to attack, so use SSL to access your email and your social media accounts. Check each of the devices you have connected, whether it is a mobile phone, laptop, or something else like a Wi-Fi connected fridge. Android users, you can download some free security software here.
